Main Features

  • Micro-computerization: Adopting a high-performance CPU chip, high-precision AD conversion technology, and SMT patch technology, it can complete multi-parameter measurement, temperature compensation, automatic conversion of range, and self-test of the instrument, with high precision and good repeatability.
  • High reliability: no complicated function switch adjustment knob.
  • Strong anti-interference ability: current output and alarm relay adopt photoelectric coupling isolation technology, strong anti-interference ability, and realize remote transmission.
  • Automatic alarm function: alarm signal isolated output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis withdrawal.
  • Network function: isolated current output and RS485 communication interface; the upper and lower limits of current corresponding to pH output can be set arbitrarily.
  • Automatic conversion of the pH value of the standard liquid: the temperature curve of the standard liquid is pre-stored, and the pH value of the standard liquid at the set temperature is automatically converted during calibration.
  • Automatic identification of incorrect calibration: If the user uses the standard buffer incorrectly during calibration, the instrument will be prompted automatically.

JCMIK-PH8.0 Online PH Meter

BCST online pH meter employs a stabilization feature that prevents the transmitter from accepting a buffer pH reading that has not reached a prescribed level of stabilization in terms of pH change per time. This feature helps eliminate the common problem of not allowing enough time for the pH to approach the buffer value, leading to a lower observed slope and higher than necessary slope correction during calibration. Online pH meters must be regularly “buffered” with solutions of known pH to establish the calibration. They are typically formed of glass electrodes and are quite fragile.

The BCST online pH meter is commonly used in various applications to accurately measure and transmit pH levels. One common application is in the water treatment industry. Online pH meters are used to monitor and control the pH of water in treatment processes to ensure that it falls within the desired ranges for effective purification. In the pharmaceutical industry, online pH meters play a crucial role in maintaining the pH of solutions during drug manufacturing. They are also utilized in agriculture for soil and irrigation management and in research laboratories for experiments involving chemical reactions or pH-sensitive biological processes. Additionally, online pH meters are used in food and beverage production. To maintain product quality and safety, monitor the acidity or alkalinity of products, such as wine or dairy.
